Two extremely old planets have been found orbiting a star that formed a mere billion years after the big bang. The problem is that there wasn't a ton of planet building material around yet at that time...furthermore, the star being orbited is the most metal-deficient star ever recorded to have planets around it...so how did the planets form and what can we learn from them?
